Abstract
Description
Technical Field
[0001] This invention relates to the field of stranding machines, and in particular to a stranding machine structure. Background Technology
[0002] A stranding machine, as the name suggests, is a specialized mechanical device that tightly strands multiple single-strand metal wires together according to specific rules to form a multi-strand conductive wire bundle with specific properties. It typically consists of a wire feeding device, a stranding main unit, a wire separating plate, a wire paralleling die, a traction device, a control system, and a wire take-up device.
[0003] In practical use, the stranding machine can draw multiple single wires from their respective feed reels, adjust them to the set tension through the tension control system, and then the single wires pass through the separator plate in an orderly manner and enter the stranding area. The bow or cage rotates at high speed under the drive of the motor. The rotational motion forces the single wires passing through it to move in a spiral motion around the central axis and twist together. The initially stranded wire bundle immediately passes through the winding die, is compacted and shaped into the required cross-sectional shape, and the traction device pulls the stranded wire forward at a set speed. The take-up device neatly winds the finished stranded wire onto the take-up reel. The control system coordinates the actions of each part to ensure that the ratio of the cage speed (N) to the traction speed (V) is constant, thereby obtaining the set stranding pitch (P=V / N), thus achieving a highly efficient and automated processing effect.
[0004] However, during actual processing, the applicant found that although the parallel die has the conditions for displacement adjustment, due to the lack of limiting on the transmission structure, the parallel die will have a slight displacement deviation due to the vibration of the overall device during operation, which in turn will change the actual "twisting point" position and affect the processing quality of the overall device. Secondly, it is an objective fact that the parallel die will have a slight synchronous sway due to the vibration of the overall device during operation. However, the existing technology lacks the conditions to monitor the actual operating status of the parallel die when needed, making it difficult for operators to detect abnormalities in a timely manner.

[0020] 1. A displacement transmission structure for the assembly formed by the motor assembly, lead screw, guide rod, T-type bevel gear box, and the first and second transmission ends on the T-type bevel gear box is formed. In subsequent use in conjunction with the assembly of the paralleling die and the adjusting support, the motor assembly will drive the lead screw through the second transmission end, the T-type bevel gear box, and the first transmission end, and the lead screw will mesh with the adjusting support. Under the guidance of the guide rod, the adjusting support and the paralleling die will automatically adjust their linear displacement until the paralleling die finds an optimal twisting point, so that the sub-lines close smoothly, the stress is moderate, and the structure is stable and round. After displacement, the paralleling die and the adjusting support will be mechanically limited by the servo brake motor inside the motor assembly to ensure the stability of the paralleling die and the adjusting support during operation.

Detailed Implementation
[0032] The technical solution of the present invention will be clearly and completely described below with reference to preferred embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] like Figures 1-6 A stranding machine structure includes a cage stranding machine 1 and a workbench 3. The cage stranding machine 1 is fitted with an outer cover 2. The top of the workbench 3 is provided with a wire-connecting mold 4 aligned with the output direction of one side of the cage stranding machine 1 and an adjusting support 5. The adjusting support 5 is installed as a support structure between the wire-connecting mold 4 and the workbench 3. The top of the workbench 3 is installed with a composite frame plate 6 that is movably connected to the adjusting support 5. The composite frame plate 6 is fitted with a lead screw 7 and a guide rod 22. The surface of the lead screw 7 is threaded with a nut fitted in the middle of the adjusting support 5. One end of the guide rod 22 passes through the side structure at the bottom of the adjusting support 5. The bottom of the adjusting support 5 is provided with clearance grooves at both the front and rear ends. A linkage limiting component 8 is fitted in the clearance groove, and the bottom of the linkage limiting component 8 is magnetically connected to an electromagnet 9 installed on the top of the workbench 3.
[0034] The end of the lead screw 7 is fitted with the corresponding side wall structure of the composite frame plate 6 through the bearing, thereby ensuring the stability of the lead screw 7 during subsequent rotation adjustment. One end of one of the lead screws 7 passes through one side wall of the composite frame plate 6 and extends to the outside of the composite frame plate 6, providing a structural foundation for the connection of the subsequent related power structure and meeting the needs of convenient installation and use. The linkage limit component 8 includes a support shaft 81 and an I-shaped sleeve 82. The support shaft 81 is fixedly fitted inside the middle of the relief groove, and the inner middle of the I-shaped sleeve 82 is fitted outside the middle of the support shaft 81. At this time, the I-shaped sleeve 82 and the support shaft 81 are in a fitted and inseparable state. The top of the T-shaped iron plate 83 is fixed on the middle surface of the I-shaped sleeve 82. The bottom surface of the T-shaped iron plate 83 is attached to the magnetic attraction surface of the top of the electromagnet 9 and can be magnetically limited by the electromagnet 9 after it is opened, thereby ensuring the stability of the adjustment support 5 movement adjustment, and thus ensuring the continuous parallel processing operation effect of the parallel die 4.
[0035] During use, the busbar and multiple sub-wires are processed by the cage stranding machine 1 and then paralleled through the conical die hole inside the paralleling die 4. When it is necessary to fine-tune the specific position of the paralleling die 4 during the initial debugging stage, the electromagnet 9 can be turned off to temporarily release the magnetic attraction limit on the T-shaped iron plate 83. The screw 7 is turned so that it engages with the transmission adjustment support 5, which in turn causes the adjustment support 5 to drive the paralleling die 4 to move left and right until the position of the paralleling die 4 meets the usage requirements, that is, to find an optimal stranding point position so that the sub-wires can be smoothly joined, the stress is moderate, and the structure is stable and round. After completion, the electromagnet 9 is turned on again to restore the magnetic attraction limit on the T-shaped iron plate 83.
[0036] like Figures 5-6 The inner side of the I-shaped sleeve 82 is fitted with the middle of the support shaft 81 by snap-fit. The end of the support shaft 81 is fitted with a spring 84, and the two ends of the spring 84 are respectively fixed to the inner wall of the relief groove and the corresponding end surface of the I-shaped sleeve 82. This provides an installation foundation for the structure of subsequent operations, so as to expand other uses on the basis of the existing device to meet different usage needs.
[0037] The end face of the I-shaped sleeve 82 is fixed with a hemispherical pressure block 20. The surface of the middle part of the hemispherical pressure block 20 is movably connected to a pressure sensor 19 installed on the inner wall of the relief groove. Thus, the extended bracket 10 and the T-shaped iron plate 83 are used as position positioning references. The displacement deviation of the adjusting support 5 and the paralleling mold 4 in the actual paralleling process is fed back by the pressure data change generated by the pressure sensor 19 due to the pressure of the hemispherical pressure block 20 moving synchronously with the adjusting support 5.
[0038] An extension bracket 10 is installed on one side of the workbench 3. A T-shaped bevel gear box 11, a motor assembly 15, and a manual adjustment assembly 16 are provided on the top of the extension bracket 10. A first transmission end 12, a second transmission end 13, and a third transmission end 14 are respectively provided on both sides and the front end of the T-shaped bevel gear box 11. One end of the first transmission end 12 is connected to the end of the lead screw 7 that extends to the outside of the composite frame plate 6. The motor assembly 15 and the manual adjustment assembly 16 can respectively drive the second transmission end 13 and the third transmission end 14, thereby meeting different usage problems encountered in actual use and adapting to different usage needs.
[0039] A support frame is installed between the housing surface of the T-type bevel gearbox 11 and one side of the composite frame plate 6. The motor assembly 15 includes a servo brake motor 151, a transition sleeve 152, a bolt 153, and a combination nut 154. The two ends of the transition sleeve 152 are respectively fitted onto one end of the second transmission end 13 and connected to the output end of the servo brake motor 151. Mounting holes are provided in the middle of the transition sleeve 152 and the middle of one end of the second transmission end 13. When the transition sleeve 152 and the second transmission end 13 are fitted together, the two mounting holes are... The installation channel is formed by alignment, and a bolt 153 is installed in the installation channel. One end of the bolt 153 extends to the bottom of the transition sleeve 152 and is threadedly connected to a combination nut 154. A support seat is installed between the housing surface of the servo brake motor 151 and the top of the extension bracket 10. The top surface of the transition sleeve 152 is provided with a first planar groove that fits and connects with the nut structure of the bolt 153. The bottom surface of the bolt 153 is provided with a second planar groove that fits and connects with the top surface of the combination nut 154, thereby improving the connection strength between subsequent structures.
[0040] In use, considering that the magnetic attraction of the extension bracket 10 to the T-shaped iron plate 83 cannot meet the positioning of the adjusting support 5 due to the clearance movement of the I-shaped sleeve 82, the motor assembly 15 will be used as the power source and limiting condition for adjusting the displacement of the adjusting support 5, and the pressure sensor 19 and the hemispherical pressure block 20 will be used as the detection conditions. Thus, while satisfying the automatic adjustment of the displacement of the adjusting support 5, the vibration displacement of the adjusting support 5 and the parallel mold 4 during operation will be detected in real time. The specific operation is as follows:
[0041] After the busbar and multiple sub-wires are processed by the cage stranding machine 1, they will be processed by paralleling through the conical die hole inside the paralleling die 4. When it is necessary to fine-tune the specific position of the paralleling die 4 during the initial debugging stage, the electromagnet 9 can be turned off to temporarily release the magnetic attraction limit on the T-shaped iron plate 83. Then, the servo brake motor 151 is started. The output end of the servo brake motor 151 drives the lead screw 7 to rotate through the locking part formed by the transition sleeve 152, bolt 153 and combination nut 154, the second transmission end 13 and the first transmission end 12, so that the lead screw 7 meshes with the transmission adjustment support 5. Then, the adjustment support 5 drives the paralleling die 4 and the linkage limit component 8 to adjust the displacement in the left and right directions until the position of the paralleling die 4 meets the usage requirements, that is, finds an optimal stranding point position, so that the sub-wires can be smoothly closed, the stress is moderate, and the structure is stable and round.
[0042] After the adjusting support 5 and the parallel die 4 have been moved to the designated position, the electromagnet 9 is activated. The magnetic surface of the electromagnet 9 magnetically attracts and limits the T-shaped iron plate 83 that has come to a stop after displacement. During the parallel processing of the adjusting support 5 and the parallel die 4, the working vibration generated by the parallel die 4 and the adjusting support 5 will be synchronously transmitted to the pressure sensor 19 installed in the clearance groove inside the adjusting support 5. Then, the pressure sensor 19 actively contacts the hemispherical pressure block 20 to generate pressure data changes. Subsequently, through the existing background control terminal, the stability of the parallel die 4 and the adjusting support 5 can be understood by the difference between the maximum and minimum values while continuously obtaining pressure data, so as to deal with abnormal shaking in time.
[0043] like Figures 1-4 The top of the composite frame plate 6 is covered with an auxiliary cover plate 17. The middle of the auxiliary cover plate 17 has a sliding groove that engages with the adjusting support 5. The outer side of the middle of the adjusting support 5 is fitted with a linkage sealing plate 18 that can cover and seal the sliding groove. The length and width of the linkage sealing plate 18 are both greater than the length and width of the sliding groove. Ventilation filters are nested in the front and rear ends of the composite frame plate 6 and in the auxiliary cover plate 17. The bottom of the corner structure of the auxiliary cover plate 17 and the corresponding corner structure of the top of the composite frame plate 6 can be installed with screws, which facilitates subsequent disassembly and replacement.
[0044] During use, considering the dusty environment, dust protection is provided for the structures on the top of the workbench 3 by using ventilation filters installed in the composite frame plate 6, ventilation filters installed in the auxiliary cover plate 17, and the linkage sealing plate 18. The specific operation is as follows:
[0045] During the transmission displacement of the paralleling mold 4 and the adjusting support 5, the slide provides clearance space for the movement of the paralleling mold 4 and the adjusting support 5. The clearance part of the slide that is not used will be sealed and covered by the linkage sealing plate 18. In this way, while avoiding interference with the movement of the paralleling mold 4 and the adjusting support 5, the various structures set on the top of the workbench 3 can always be kept relatively closed and dustproof, which improves the service life of the lead screw 7, guide rod 22 and the connection structure of the adjusting support 5.
[0046] like Figures 5-7 The third transmission end 14, away from the T-shaped bevel gearbox 11, has a square hole 21. The manual adjustment assembly 16 includes a transmission shaft 161. One end of the transmission shaft 161 is fixed with a square rod 163 that can engage with the square hole 21. A bearing is fitted on the outer side of the middle of the transmission shaft 161, and a guide sleeve 162 installed on one side of the composite frame plate 6 is engaged with the bearing. This satisfies the manual adjustment requirements of the lead screw 7 and further improves the flexibility of the overall device during use. A steering wheel is fixed on the other end of the transmission shaft 161, and a limit ring is fitted on the outer side of one end of the transmission shaft 161 to prevent the transmission shaft 161 from disengaging from the guide sleeve 162.
[0047] In use, considering the limitations of manual adjustment of the lead screw 7 and displacement adjustment of the parallel die 4 and adjusting support 5, the manual adjustment component 16 is used in combination with the inseparable support shaft 81 and I-shaped sleeve 82. The specific operation is as follows:
[0048] After the busbar and multiple sub-wires are processed by the cage stranding machine 1, they will be processed by paralleling through the conical die hole inside the paralleling die 4. When it is necessary to make a fine adjustment to the specific position of the paralleling die 4 during the initial debugging stage, the electromagnet 9 can be turned off to temporarily release the magnetic attraction limit on the T-shaped iron plate 83.
[0049] Remove and separate the bolt 153 and the combination nut 154 from the transition sleeve 152. Push the drive shaft 161 until the square rod 163 on one end of the drive shaft 161 engages with the corresponding square hole 21. After completion, rotate the drive shaft 161 so that the drive shaft 161 drives the lead screw 7 to rotate through the square rod 163, the third transmission end 14 and the first transmission end 12. Then, the lead screw 7 engages with the transmission adjustment support 5, which in turn drives the paralleling die 4 to adjust its displacement in the left and right directions until the position of the paralleling die 4 meets the usage requirements, that is, finds an optimal twisting point position so that the sub-wires can be smoothly joined, the stress is moderate, and the structure is stable and round. After completion, turn on the electromagnet 9 again to restore the magnetic attraction limit on the T-shaped iron plate 83.
